BACKGROUNDLung transplantation offers definitive treatment for end-stage pulmonary disease, but graft survival remains inferior to other solid organ transplants. A key driver of graft loss is antibody-mediated rejection triggered by donor-recipient HLA mismatch. Although HLA matching is not currently used in lung allocation due to organ scarcity and urgency of transplant, understanding its impact could improve risk stratification and outcomes. This study aimed to assess the effect of HLA compatibility on lung graft survival using a large multicenter database, and to explore whether this relationship varies by transplant indication.METHODSWe conducted a retrospective cohort study of 37,091 lung transplant recipients in the UNOS/OPTN database. Patients were grouped by HLA mismatch (0-2 versus 3-6) and stratified by indication. Multivariate Cox regression and Kaplan-Meier analyses assessed adjusted associations with graft survival.FINDINGSHLA-DR mismatch was associated with increased graft failure risk at one year (HR 1.38; 95% CI 1.00-1.90; p=0.048) and five years (HR 1.20; 95% CI 1.03-1.40; p=0.020). Stratified analyses showed this effect was found exclusively in those with COPD or interstitial pneumonia. In COPD, HLA-DR mismatch significantly increased failure risk at one and five years (HR 2.88, CI 1.34-6.19, p=0.007; HR 1.14, CI 1.03-1.40, p=0.020). In interstitial pneumonia, five-year graft failure risk also rose with mismatch (HR 1.28; CI 1.03-1.58; p=0.026).INTERPRETATIONThe present study is the first to demonstrate that HLA-DR mismatch adversely affects lung graft survival in an indication-specific manner. This finding supports the development of indication-specific strategies in post-transplant surveillance and immunosuppression.
肺移植为终末期肺部疾病提供了明确的治疗方法,但移植物的存活率仍然不如其他实体器官移植。移植损失的一个关键驱动因素是由供体-受体HLA不匹配引发的抗体介导的排斥反应。尽管由于器官稀缺和移植的紧迫性,HLA匹配目前尚未用于肺分配,但了解其影响可以改善风险分层和结果。本研究旨在利用大型多中心数据库评估HLA相容性对肺移植存活的影响,并探讨这种关系是否因移植指征而异。方法我们对UNOS/OPTN数据库中的37,091名肺移植受者进行了回顾性队列研究。患者按HLA不匹配(0-2对3-6)分组,按适应证分层。多变量Cox回归和Kaplan-Meier分析评估了与移植物存活的调整相关性。发现shla - dr不匹配在1年(HR 1.38; 95% CI 1.00-1.90; p=0.048)和5年(HR 1.20; 95% CI 1.03-1.40; p=0.020)与移植物衰竭风险增加相关。分层分析显示,这种效应仅在COPD或间质性肺炎患者中发现。在COPD患者中,HLA-DR不匹配显著增加了1年和5年的衰竭风险(HR 2.88, CI 1.34-6.19, p=0.007; HR 1.14, CI 1.03-1.40, p=0.020)。在间质性肺炎中,5年移植物失败的风险也随着失配而增加(HR 1.28; CI 1.03-1.58; p=0.026)。本研究首次证明HLA-DR不匹配以适应症特异性的方式对肺移植存活产生不利影响。这一发现支持移植后监测和免疫抑制的适应症特异性策略的发展。

BACKGROUNDHigh-density lipoprotein (HDL) cholesterol exerts anti-inflammatory, antioxidative, and endothelial-protective effects, yet its role in interstitial lung abnormalities (ILA) remains unclear.METHODSWe analyzed baseline screening from heavy smokers who participated in the Korean national lung cancer screening program (2019-2021). HDL cholesterol was measured at two prescreening time points (remote and immediate) and categorized as normal or low. Participants were also classified into four HDL trajectories: normal-to-normal, low-to-normal, normal-to-low, and low-to-low. We used logistic regression to estimate odds ratios (ORs) for ILA, adjusting for demographic characteristics, body mass index, lifestyle factors, comorbidities, income status, lipid profiles, and statin use.RESULTSAmong 159 729 participants (mean age, 61.7 years; 98.2% men), ILA was detected in 2.9%, with higher prevalence in those with low HDL at immediate prescreening compared with normal HDL (3.5% versus 2.7%). Participants with low HDL cholesterol had a higher proportion of obesity (6.1% versus 3.5%) and more frequent statin use (40.0% versus 34.4%) than those with normal HDL cholesterol. Compared with the normal-to-normal group (2.6%), ILA prevalence increased across the low-to-normal (3.1%), normal-to-low (3.5%), and low-to-low (3.6%) groups. Low HDL at immediate prescreening was associated with a 28% higher risk of ILA (95% CI, 1.19-1.38; p<0.001). Compared with normal-to-normal HDL, the odds of ILA were higher in low-to-normal (adjusted OR, 1.17; 95% CI, 1.06-1.29; p=0.002), normal-to-low (adjusted OR, 1.30; 95% CI, 1.18-1.44; p<0.001), and low-to-low groups (adjusted OR, 1.32; 95% CI, 1.20-1.45; p<0.001).CONCLUSIONSLow HDL cholesterol was associated with a higher risk of ILA.
背景:高密度脂蛋白(HDL)胆固醇具有抗炎、抗氧化和内皮保护作用,但其在肺间质性异常(ILA)中的作用尚不清楚。方法:分析参与韩国国家肺癌筛查计划(2019-2021)的重度吸烟者的基线筛查结果。在两个预筛选时间点(远程和即时)测量高密度脂蛋白胆固醇,并将其分类为正常或低。参与者也被分为四种HDL轨迹:正常到正常,低到正常,正常到低,低到低。我们使用逻辑回归来估计ILA的优势比(or),调整了人口统计学特征、体重指数、生活方式因素、合并症、收入状况、脂质谱和他汀类药物的使用。结果在159 729名参与者(平均年龄61.7岁,98.2%为男性)中,有2.9%的人检测到ILA,在立即筛查时HDL水平较低的人群中,ILA的患病率高于HDL水平正常的人群(3.5%对2.7%)。与HDL胆固醇正常的参与者相比,低HDL胆固醇的参与者有更高的肥胖比例(6.1%对3.5%)和更频繁地使用他汀类药物(40.0%对34.4%)。与正常至正常组(2.6%)相比,低至正常组(3.1%)、正常至低组(3.5%)和低至低组(3.6%)的ILA患病率均有所增加。立即筛查时低HDL与ILA风险增加28%相关(95% CI, 1.19-1.38; p<0.001)。与正常到正常的HDL相比,低到正常(校正OR, 1.17; 95% CI, 1.06-1.29; p=0.002)、正常到低(校正OR, 1.30; 95% CI, 1.18-1.44; p<0.001)和低到低组(校正OR, 1.32; 95% CI, 1.20-1.45; p<0.001)的ILA的几率更高。结论低密度高密度脂蛋白胆固醇与ILA的高风险相关。

Background: Transthoracic shear-wave elastography (SWE) facilitates differentiation between benign and malignant lesions. This pragmatic randomised controlled trial aimed to validate the effectiveness and safety of SWE-guided transthoracic biopsy for diagnosing subpleural lung lesions.

Methods: Eligible patients with peripheral lung lesions suspicious for lung malignancy and suitable for biopsy were randomised in a 1:1 ratio to the SWE-guided or conventional ultrasound-guided transthoracic biopsy groups. Rapid on-site cytological evaluations were performed to guide adjustments to biopsy target areas. The primary outcome was the diagnostic yield, defined as the proportion of biopsies yielding a specific benign or malignant diagnosis on cytology or histology. Secondary outcomes included biopsy duration and the combined incidence of post-biopsy complications.

Results: From May 2019 to June 2023, a total of 413 patients were randomised. Ultimately, 205 patients in the SWE group and 206 in the conventional group were included in the intention-to-diagnose analysis. The SWE group achieved a significantly higher diagnostic yield compared with the conventional group (94.6% versus 88.3%; risk ratio 1.07, 95% CI 1.01-1.14; p=0.02) and a shorter biopsy duration (median (interquartile range) 12 (9-15) versus 13 (10-18) min; Hodges-Lehmann median difference -1.0 (95% CI -3.0-0) min; p=0.003). The combined incidence of pneumothorax, haemoptysis and haemothorax was comparable between the groups (2.4% versus 2.9%; risk ratio 0.84, 95% CI 0.26-2.70; p=0.77).

Conclusions: SWE-guided transthoracic biopsy increased the diagnostic yield and reduced the biopsy duration for subpleural lung lesions without increasing the risk of complications.

背景:经胸横波弹性成像(SWE)有助于良恶性病变的鉴别。这项实用的随机对照试验旨在验证超声引导下经胸活检诊断胸膜下肺病变的有效性和安全性。方法:将符合条件的肺周围病变疑似恶性肿瘤且适合活检的患者按1:1的比例随机分为超声引导下或常规超声引导下的经胸活检组。快速现场细胞学评估进行指导调整活检靶区。主要结果是诊断率,定义为细胞学或组织学上产生特定良性或恶性诊断的活检比例。次要结局包括活检时间和活检后并发症的综合发生率。结果:2019年5月至2023年12月,共纳入413例患者。最终,205例SWE组患者和206例常规组患者被纳入意向诊断分析。与常规组相比,SWE组的诊断率明显更高(94.6% vs 88.3%;风险比:1.07;95% CI: 1.01-1.14; p=0.02),活检时间更短(中位12分钟[9-15]对13分钟[10-18];Hodges-Lehmann中位差为-1.0分钟(95% CI: -3.0-0);p = 0.003)。气胸、咯血和血胸的合并发生率在两组间具有可比性(2.4% vs 2.9%;风险比:0.84;95% CI: 0.26-2.70; p=0.77)。结论:超声引导下的经胸活检提高了胸膜下肺病变的诊断率,缩短了活检时间,但未增加并发症的风险。

Aging is a crucial factor in the development of chronic lung diseases, including chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF), and lung cancer. Marking the 10th anniversary of the original "Hallmarks of the aging lung" published in this Journal, we present an updated review highlighting key cellular and molecular features of aging that drive the onset and progression of these conditions. Aging stands as the most significant risk factor for chronic lung diseases, which are characterised by structural and functional changes such as reduced elasticity, persistent inflammation, and impaired repair capacity. Recent evidence confirms that nearly all recognised hallmarks of aging play a role in the pathogenesis of these diseases. Notably, extracellular matrix (ECM) dysregulation - first proposed as a lung aging hallmark in 2015 - has become an integral aspect of aging in lung disease. Environmental exposures, such as cigarette or wildfire smoke, accelerate age-related changes by increasing oxidative stress, promoting cellular senescence, and disrupting tissue homeostasis. In lung cancer, aging contributes to genomic alterations, epigenetic dysregulation, immune evasion, and therapeutic resistance. Additionally, the roles of extracellular vesicles and microbiome changes in shaping these aging phenotypes are emerging areas of research. Early clinical studies are now targeting specific aging hallmarks, such as cellular senescence, with the goal of reducing age-related pathology and improving outcomes. Overall, integrating aging biology into lung disease research paves the way for innovative diagnostic and therapeutic strategies that address common molecular mechanisms across multiple chronic lung conditions.
衰老是慢性肺部疾病发展的关键因素,包括慢性阻塞性肺疾病(COPD)、特发性肺纤维化(IPF)和肺癌。为了纪念《柳叶刀》发表“肺老化的标志”十周年,我们提出了一项最新的综述,强调了衰老的关键细胞和分子特征,这些特征驱动了这些疾病的发生和进展。衰老是慢性肺部疾病最重要的危险因素,其特征是结构和功能变化,如弹性降低、持续炎症和修复能力受损。最近的证据证实,几乎所有已知的衰老特征都在这些疾病的发病机制中发挥作用。值得注意的是,细胞外基质(ECM)失调——在2015年首次被提出作为肺部衰老的标志——已经成为肺部疾病衰老的一个组成部分。环境暴露,如香烟或野火烟雾,通过增加氧化应激,促进细胞衰老和破坏组织稳态来加速与年龄相关的变化。在肺癌中,衰老导致基因组改变、表观遗传失调、免疫逃避和治疗抵抗。此外,细胞外囊泡和微生物组变化在塑造这些衰老表型中的作用是新兴的研究领域。早期临床研究现在针对特定的衰老特征,如细胞衰老,目的是减少与年龄相关的病理和改善结果。总的来说,将衰老生物学整合到肺部疾病研究中,为解决多种慢性肺部疾病的共同分子机制的创新诊断和治疗策略铺平了道路。

Marking the 10th anniversary of the original \"Hallmarks of the aging lung\" published in this Journal, we present an updated review highlighting key cellular and molecular features of aging that drive the onset and progression of these conditions. Aging stands as the most significant risk factor for chronic lung diseases, which are characterised by structural and functional changes such as reduced elasticity, persistent inflammation, and impaired repair capacity. Recent evidence confirms that nearly all recognised hallmarks of aging play a role in the pathogenesis of these diseases. Notably, extracellular matrix (ECM) dysregulation - first proposed as a lung aging hallmark in 2015 - has become an integral aspect of aging in lung disease. Environmental exposures, such as cigarette or wildfire smoke, accelerate age-related changes by increasing oxidative stress, promoting cellular senescence, and disrupting tissue homeostasis. In lung cancer, aging contributes to genomic alterations, epigenetic dysregulation, immune evasion, and therapeutic resistance. Additionally, the roles of extracellular vesicles and microbiome changes in shaping these aging phenotypes are emerging areas of research. Early clinical studies are now targeting specific aging hallmarks, such as cellular senescence, with the goal of reducing age-related pathology and improving outcomes. Overall, integrating aging biology into lung disease research paves the way for innovative diagnostic and therapeutic strategies that address common molecular mechanisms across multiple chronic lung conditions.","PeriodicalId":12265,"journal":{"name":"European Respiratory Journal","volume":"8 1","pages":""},"PeriodicalIF":24.3,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147439216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
